Scientists go to extremes to monitor Arctic permafrost loss

Researchers are studying coastal erosion in the Arctic — where sea-ice extent has recently reached record lows, permafrost soils are rapidly thawing and the coast is retreating at an astonishing rate of 15 meters per year, more than double the rate of several decades ago.

Humans are influencing some extreme weather events, but not all

In 2012, the world experienced dozens of extreme weather events, including droughts, heat waves, cold spells, extreme rainfalls, big storms like Superstorm Sandy, and a record-low Arctic sea-ice extent. Teasing apart the factors that create extreme weather is a challenge for scientists, especially when it comes to determining whether human-induced climate change plays a role. Recently, 18 different research teams — comprising 80 scientists — took on that challenge.

Climate, terroir, and wine: What matters most in producing a great wine?

Weather and climate have played decisive roles throughout human existence — where and how cultures developed, where they migrated and even how some died out. The most successful early civilizations were those that developed strong agrarian systems based on what crops were most compatible with the climate. If conditions changed for one reason or another, people migrated to areas with a more suitable environment to grow a certain crop or raise specific animals.

Travels in geology: Antarctica: Following in the footsteps of giants

In fall 2012, when I told friends and colleagues that I was heading south for a few weeks, they assumed that I, like many other northeasterners, was going to Florida or the Bahamas for a break from winter weather. Instead, I was headed to the iciest and southernmost place on Earth: Antarctica.

World War G: Zombies, energy and the geosciences

In lieu of doing a "year in review" issue this year, EARTH asked our staff and some frequent contributors to write a short commentary on something that grabbed their attention in 2013. We gave everyone carte blanche. What follows is a collection of extremely varied, often very personal insights into how the planet impacted each individual. In this commentary, EARTH contributing editor Michael Webber draws parallels between zombies and the geosciences.

Science denialism: The problem that just won’t go away

In lieu of doing a "year in review" issue this year, EARTH asked our staff and some frequent contributors to write a short commentary on something that grabbed their attention in 2013. We gave everyone carte blanche. What follows is a collection of extremely varied, often very personal insights into how the planet impacted each individual. In this commentary, EARTH contributor and cartoonist Callan Bentley discusses his run-ins with science denialism.

Corals find a way to adapt?

Temperature records indicate that ocean waters started to warm shortly after industrial revolution, about the turn of the 20th century. In the past few decades, corals around the world have become endangered because of rising water temperatures. However, a new study suggests that corals may be able to adapt to some of that warming.

Environmental changes contributed to Mediterranean cultural crisis

About 3,200 years ago, urban cultures thrived in the Eastern Mediterranean until invasions in coastal and inland areas, compounded by agricultural decline, created a regional crisis.

A hurricane by any other name: How Sandy changed the way we issue storm warnings

As last year's Superstorm Sandy bore down on the Northeast, storm watchers could tell it would be worse than anything seen in decades, but the storm warnings were missed by many. One disconnect came from strict protocols about how federal agencies issue warnings. Since the devastating storm, federal officials have been revising their protocols to avoid a repeat situation. Will it be enough?

Map provides clues to natural protection of U.S. coastal communities

Devastating storms like Hurricanes Sandy and Katrina have left many coastal residents wondering how to protect life and property from future catastrophes. In a study published this week in Nature Climate Change, researchers suggest the best protection from storms and rising sea levels in the U.S. may entail a combination of engineering and conservation.
